The BEST Matrimonial Attorney!

This was the best money I ever spent. I had non-marital assets to protect and Mark knew how to finesse the situation at every turn to make sure they were "off the table". It was obvious that he is well-respected by his peers, judges and mediators. He demonstrated nothing but the highest ethical sta...ndards throughout the process and has true empathy for his clients. He is great at reading people and sizing them up. He helps you stay objective and focused at a time when it is very easy to get lost in a very emotional process. If you need to hire a divorce lawyer, hire Mark before the other side gets him first!

Texas Super Lawyer!!

Mark is the best of the best. When he gets into "trial mode" you almost feel sorry for the other side because they don't stand a chance against his no holds barred approach. Mark handled our custody case with skill, professionalism and compassion. He seemed truly concerned for the safety of our ...child and got us more than what we could have hoped for. I've recommended Mark to family and friends and they too have been beyond happy with the results Mark Williamson has achieved for them. He and his staff were always there when we needed them, whether it was to answer questions, explain the upcoming process or just to reassure us. If I ever need an attorney for a family matter again, Mark Williamson will be the first call I make.

My ex-husband hated Mark Williamson, need I say anything more?

While my ex-husband and his series of 4 attorneys fabricated malicious personal attacks against me, Mark never chose to take their bait or behave like that. With a laser focus on only the issues that matter in family law, he calmly but relentlessly cross examined my ex until he had extracted the inf...ormation that benefited me and exposed my ex for the deceiver that he is. My ex, a testifying expert who makes his living in a court room setting, went from self-assured cockiness to a slouching mass of wimpers after several hours of questions from Mark. In court I always had a sense that Mark and Monica were well respected by their peers and the judges. Monica had a patience beyond understanding along with her excellent legal skills. It was difficult not to vent my frustrations about my ex and the legal process without Monica getting caught in my rant. I spent a lot of time apologizing; she spent a lot of time forgiving me. (I hope she forgives me.) In the worst chapter of my life, they were both there to encourage and assure me that I would be alright, that I would survive. It was a tough journey and I never felt I had chosen unwisely. For my divorce I interviewed only Mark, who was recommended to me by my family practice doctor, and have never looked back.

Everything you need in an attorney

Mark was patient and poised throughout my entire ordeal. He was someone I could just "trust to take care of things" when all I wanted to do was relax and focus on my family and work without having to worry about the lawsuit. He was extremely knowledgeable would think several steps ahead to stay ahe...ad of the other council. He is incredibly knowledgeable of the judges, and what the judges want and expect. His staff was incredibly helpful and friendly, kind and compassionate. His paralegal Shirley is smart and extremely quick to return calls when Mark was out of pocket. Mark is someone you want on your side and a formidable opponent for opposing attorneys.

If you want an assertive attorney, Mark is the way to go!!!

Mark Williamson is the best family law attorney I have ever encountered. I have previously worked with two other attorneys regarding my divorce and custody issues. My divorce had been dragged out for a period of two and a half years prior to hiring Mark. In two months Mark was able to complete my div...orce and terminate the parental rights of a very violent person. I am so very thankful that Mark was willing to take on my complicated case. He was always very prompt to return phone calls and e-mails. Not only was he prompt but I always immediately received a copy of all documents pertaining to my case. He is extremely knowledgeable, very empathetic and understanding. Mark is a very aggressive attorney who will fight for his clients.

Family lawyer | May 22

Relationship: Opposing Counsel on matter

"I had a case against Mr. Williamson in 2011 and in all my dealings with Mark I found him to be an extremely intelligent, tough, and well prepared attorney that definitely knew his stuff. I'll always remember that despite the years of experience he had on me, he treated me with respect throughout the process. Although tough in the courtroom, his demeanor with fellow lawyers behind the scenes was exactly how it should be. Mark knew when to be diplomatic and also when to flex his legal muscles. I learned a lot going up against Mr. Williamson, and even modeled some of my own practice methods after his. In addition, his office staff was always unbelievably courteous and helpful, even though we were adversaries. I highly recommend Mark Williamson to anyone seeking a family law attorney, and to be honest I'd probably choose him if I ever needed a family attorney myself."

I certainly am not itching to be divorced from my own wife, but if it were to happen, Mark would be on the short list of lawyers to whom I would turn to handle my own affairs."
